A movie is in the works. You can check out developments at SmallBoysTheMovie.com as well as The Battle Off Samar Squidoo site.
From the Naval Historical Foundation:
We recently learned about a new film project being developed about the Battle off Samar. An independent group of filmmakers is working on a virtual recreation of this pivotal American victory in the Pacific during World War II – one of the great “upsets” in naval history. This ambitious project is currently in the research and development process, with a targeted shooting date of 2013.
